The length of a rectangle is fixed at 24 cm. What widths will make the perimeter greater than 7c cm?
The width must be greater than:

must be a typo
since the length is 24 cm, the perimeter must be greater than 48 cm 
Sorry it said greater than 76 cm not 7c.

2L + 2W < 76
Insert your value for L and solve for W.
I hope this helps. 
Thanks I think it did...just to be sure:
2(24) +2w< 76
48 +2w <76
2w < 28
w < 14
So the answer would be 14
